Biomimetic Bond Building Serum
A true game-changer in hair repair, this biotech-powered leave-on serum redefines what is possible in the bond building category. Built on over 15 years of cutting-edge proteomics research, KeraBio™ K31 harnesses vegan biomimetic keratin to rebuild and recharge hair from within, bonding directly to keratin inside the cortex for deep, lasting strength. Proven to deliver 100% stronger hair than the leading bond builder, its results only get better with continued use. Extensive data demonstrates that KeraBio K31 provides molecular repair to reverse years of hair damage, restoring internal structure and resilience to levels compatible with virgin hair. Elegant, high-performance, and rooted in science, this next generation serum represents a new era in hair repair performance.
